PUMP FOR ARTESIAN WELLS.

SPECIFICATION forming part of Letters PatentNo. 735,661, dated August 4,1903. Application iiled September 30, 1901. Serial No. 77,033. (Nomodel.)

T0 all whom, it nuby'colwern:

Be it known that 1, THOMAS H. GALLAGHER, acitizen ofthe United States ofA1nerica,residing at Carnegie, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Pumpsfor Artesian Vells, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention comprises a valve-casing consisting of lower and uppermembers detach- 1 ably secured together, the lower member havlockinglugs or iins at its lower end beneath the partition and an annulariiange seating on the annular flange of the partition, a cap having acentral rod-opening and secured to the collar, an upper member withwhich a section of the pump barrel or tube is connected and `receivingthe upper end of the collar and having a lower end formed with anannular series of upper valve-recesses located above the lowervalve-recesses spaced from the partition and fitting in the upper end ofthe lower member, and valves adapted to play in the space between thelower and upper valve-recesses, as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in whichlFigure 1 is in part a side elevation and in part a Vertical longitudinalsection of my improvement-in pumps for Artesian wells. Fig. Y

2 is a top plan view of the lower member, the

` guide-sleeve and ball-valves being omitted.

Fig. 3 is a side elevation of the guide-sleeve. Fig. 4 is a bottom viewthereof.

10 is the working barrel or tube of a pump for Artesian wells, having aninteriorly-screwthreaded upper end 11, receiving theeXteriorly-screw-threaded neck 12 of the lower member 13 of avalve-casing. This lower member 13 has an interiorly-screw-threadedupper end 14 and a partition 15, providing a lower inlet-chamber 16 andan upper outlet.- chamber 17.

The partition 15 is formed with a central rod-opening 18 and an annularange 19, having radial recesses 2O and surrounding the centralrodopening 18, an annular series of orifices 21, each having a lowerhemispherical valve-recess 22 and located between the centralrod-opening 18 and the wall of the lower member 13, and aneXterorly-screwthreaded collar 23, surrounding the central rod-opening18.

24 represents a series of ball-valves normally seated in the .lowervalve-recesses 22 in the upper outlet-chamber 17. Vithin the collar 23and projecting downwardly into the lower inlet-chamberl is a dependingguidesleeve 25 for the pump-rod 26, provided with radial wedge-shapedlocking lugs or fins 27 at its lower end and an annular supportingflange28, located contiguous to the locking lugs or fins and seating on theannular ange 19. The guide-sleeve 24 is seated within the collar 23 bybringing the locking lugs or fins 27 into position over the radialrecesses, which will permit its lower end to pass through the central'rod-opening 18. The space between the upper en d of the guide-sleeve 25and the collar 23 provides a chamber 29, into which suitable materialmay be placed to furnish a packing for the pump-rod 26. This chamber 29is closed by an interiorly-screwthreaded flanged cap 30, having acentral rodopening 31 and secured to the collar 23.

32 is the upper member of the casing, having a central chamber 33 and anexteriorlyscrew-threaded lower end 34 fitted in theinteriorly-screw-threaded upper end 14 of the lower member 13, havingupper hemispher: ical valve-recesses 35 for the receptionof theball-valves 24, which play across the outletchamber 17 fromA theirspaced recesses.

Having thus described my invention, the following is what I claim as newtherein and desire to protect by Letters Patent:

A pump for Artesian wells comprising a IOO lower member formed with aneck at its lower end, a partition dividing the lower member into alower inlet-chamber and an upper outlet-chamber, and having, a centralrod-opening, an annular Iiange located at the base of the centralrod-opening and having radial recesses, an upwardly-extending collarproviding an extension to and surrounding the central rod-opening, andan annular series of orifices each having a hemispherical recess andlocated between the collar and the wall of the lower member, aguidesleeve having' its upper end located within the centralrod-opening, and its lower end depending from the partition and formedwith radial locking-fins and an annular flange spaced from thelocking-fins and seating on the annular fiauge of the partition, a caphaving a THOMAS H. GALLAGIIER.
